Nondisp fx of lunate, unsp wrist, subs for fx w delay heal

This code signifies a fracture of the lunate bone in the wrist that is not displaced, meaning the bone fragments are still in their normal anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "delayed healing" specifies that the bone is not mending at the expected rate.

Use this code when a patient presents for ongoing treatment of a previously diagnosed, nondisplaced lunate fracture, and clinical documentation confirms that the healing process is slower than anticipated. This would typically be seen in follow-up appointments after initial casting or splinting, where imaging or clinical assessment reveals insufficient callus formation or persistent pain beyond the usual healing timeframe.

• Ensure documentation explicitly states "nondisplaced" and "delayed healing" for the lunate fracture.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• Confirm the affected wrist (left, right, or unspecified) is clearly documented if known.
